Stadium of Light get Bloomfield Road man.
Sunderland have made their ninth summer signing after completing the free transfer of midfielder David Vaughan from Blackpool.
The 28-year-old will follow defenders Wes Brown and John O’Shea into the Wearside club in what has been a busy 24 hours.
The Wales international played a key role in getting the Seasiders into the Premier League but could not prevent them sliding back into the Championship.
Vaughan began his career as a trainee at Crewe and after a spell in Spain with Real Sociedad, joined Blackpool for £200,000 three years ago.
He will compete with fellow midfield newcomers Ahmed Elmohamady, Craig Gardner and Sebastian Larsson for a place in the starting XI.
Manager Steve Bruce has also landed goalkeeper Keiren Westwood and strikers Connor Wickham and Ji Dong-Won.
The Black Cats finished 10th in last season’s Premier League, but might have fared even better had it not been for a prolonged injury crisis, which the boss is determined not to let happen again.
“David was excellent throughout last season, including both games against us, so it’s only natural that he caught the attention of a number of top clubs,” Bruce said.
“We are delighted that he sees his future at Sunderland.
“His experience, grit and energy in midfield will be valuable assets to us and we are now looking forward to him joining up with the squad for pre-season training.”
